1.4.1 (2020-01-20)
- Implement generalized EncodedButtonConfig which can handle M=2^N-1 buttons using N pins using an optimization that makes only N calls to digitalRead() instead of M * N calls. Add examples/Encoded16To4Buttons example; rename examples/EncodedButtons to examples/Encoded8To3Buttons.
